SPECIFICATION forming part of Letters Patent No. 323,494, dated August4, 1885.

Application tiled March 10, 1885. {No model.)

To CLZZ whom it may concern.-

Be it known that I, Gnoncn M. BRAUNIN- GER, a citizen of the UnitedStates, residing at J anesville, in the county of Rock and State ofWisconsin, have invented certain new and useful Improvements inBoilerater Purifiers; and I do hereby declare the following to be afull, clear, and exact description of the invention, such as will enableothers skilled in the art to which itappertains to make and use thesame, reference being had to the accompanyingdrawings, and to letters orfigures of reference marked thereon, which form a part of thisspecification.

My invention relates to certain improvements in boiler water purifiers,for which Patent No. 294,754 was granted to me March 11, 188-1, in whichpatent two separate forms of apparatus are shown, in both of which anoutside inclosing-case having a head or cover and blow-off pipe areessential elements. In one of said forms the several apartments areretained in place, one upon another, by contact of their-flanges withthe outside inclosure, together with the central pipe. In the other formis shown a single large inner receptacle having permanentlyaffixedpartitions, such inner receptacle being suspended from the cover of thelarger outer inclosure, neither of which forms, when complete, can beinserted through the man-hole of the boiler, nor is either form capableof being separated into independent parts and inserted in the boilerwithout the aid of mechanical appliances, but must necessarily be in agreat part, at least, constructed within the boiler.

The object of my improvement is to so form the several receptacles whichalone constitute my apparatus that they may be made complete outside ofthe boiler, and in their several independent parts be readily insertedand withdrawn from the boiler, and when set up within the boiler may bethus retainedin place without either the inclosing-case, the covers, orblow-off pipe, all of which parts it is the object of my presentinvention to dispense with.

My invention is further explained byreference to the accompanyingdrawings, in which- Figure 1 is a cross-section of a boiler having mydevice therein, which is also shown in cross-section. Fig. 2 is a topview of one of the pans.

The same letters refer to like parts in both views. i

The purifying device A consists of a series of pans, a a a, placedoneupon another within the boiler, forming chambers therein. The bottompan may rest upon the top series of the fines, I) b b, or upon a bracketor frame provided especially therefor, as desired. The bottom pan isprovided with aseries of holes, a 0 0, through its vertical sides, nearthe top,

and at some little distance up from its bottom.

The bottom of this lowest pan is tight, but the other pans superimposedthereon in a successive series are each provided with an aperture, (I,through the bottom thereof, near one end of the pan, and the pans are soplaced one upon another that these apertures 11 d will not besuccessively one above another, but will alternate, one being at one endof the device and the next one at the other end of the device. Forconvenience in placing one pan upon another in position, the pans abovethe lowest one are provided around their bottom edge with a smallinwardly-extending shoulder, around and against which the top of thesucceeding pan next below is placed.

The water is supplied to the boiler in the usual way through a pipe, B,which pipe discharges the incoming water into the top pan, and in itscourse down through the pans changes from end to end of the device A asit passes down through the alternating apertures cl (1 to the bottompan, out of which it flows through the holes 0 c. In passing through theseveral chambers of this device the water flows over a series of spaceswithin the pans, which in the aggregate amounts to a long distance, andas it moves slowly it has ample time to and does deposit all mud andearthy sediment on the bottoms of the pans, and as the water is heatedwhile yet in the pans the lime in the water is precipitated upon theinner surprovided with apertures or passages commdnicating with eachother and the boiler and adapted to secrete the sediments of the waterin passing from the inlet-pipe to the boiler, and to be detached andremoved in sections from and replaced in the boiler,'substantially asand for the purpose specified.

In testimony whereof I affix my signature in presence of two witnesses.V
